Foundation Repair in Roanoke, TX

The most mixed ground in our study, a watering rule written with foundations in mind, and Grapevine Lake to the south.

Roanoke's ground is more mixed than any other town we studied around Denton. Our 25 sample points there landed on 19 different soils, more than in any of the other 32 towns. If you're trying to work out why your Roanoke house has a new crack, that variety matters: the soil under your lot may not match your neighbor's.

The Ground Under Roanoke

Roanoke sits on the west band of Denton County, though only partly. On the state geologic map, 24% of our 25 points landed on the Grayson Marl and Main Street Limestone, and 20% on the unit that holds the Pawpaw Formation, the Weno Limestone and the Denton Clay. Another 28% fell on terrace deposits, 16% on river alluvium and 12% on the Woodbine sandstone.

The soil survey reflects that mix. Of the 25 points, 16 read high or very high for shrink and swell (64%), and 5 very high (20%). The only soils that showed up more than twice:

  • Ponder loam, 3 points. It formed from the shale of the Grayson Marl and reads 4.5 on the USDA scale in its top 7 inches, then 7.5 down to 80 inches.
  • Gasil fine sandy loam, 3 points. A sandy top 13 to 17 inches deep over sandy clay loam reading just 1.8.

Sanger clay and Navo clay loam turned up twice each. Every other soil appeared once, from Tinn clay, a creek-bottom soil reading 17, to Somervell gravelly loam over limestone about 27 inches down. Lott silty clay, at one point, reads 7.5 in its top 16 inches before dropping to 4.5.

The USDA says a soil rated moderate or higher can damage buildings as it shrinks and swells, and most of Roanoke's soils read at least moderate. With this much variety, a town-wide figure only goes so far. The USDA lookup in our soil and rock guide can name the soil under your own lot, and a floor survey shows how the house is actually behaving.

Soil under Roanoke, by share of the town Share of Roanoke covered by each mapped soil series, from a 25-point sample of the USDA soil survey. Ponder, reads 7.5 below the surface: 12% of the town, peak linear extensibility 7.5 (high); Gasil, reads 1.8 below the surface: 12% of the town, peak linear extensibility 1.8 (low); Sanger, reads 9.1: 8% of the town, peak linear extensibility 9.1 (very high); Navo, reads 7.5 below the surface: 8% of the town, peak linear extensibility 7.5 (high); Tinn, reads 17: 4% of the town, peak linear extensibility 17 (very high); Branyon, reads 13: 4% of the town, peak linear extensibility 13 (very high); Slidell, reads 10: 4% of the town, peak linear extensibility 10 (very high); Burleson, reads 8: 4% of the town, peak linear extensibility 8 (high); Crockett, reads 7.5: 4% of the town, peak linear extensibility 7.5 (high); Lott, reads 7.5: 4% of the town, peak linear extensibility 7.5 (high); Medlin, reads 7.5: 4% of the town, peak linear extensibility 7.5 (high); Seagoville, reads 7.5: 4% of the town, peak linear extensibility 7.5 (high); Wilson, reads 7.5: 4% of the town, peak linear extensibility 7.5 (high); Justin, reads 4.5: 4% of the town, peak linear extensibility 4.5 (moderate); Lindale, reads 4.5: 4% of the town, peak linear extensibility 4.5 (moderate); Bastsil, reads 3.4: 4% of the town, peak linear extensibility 3.4 (moderate); Aledo, reads 2.8: 4% of the town, peak linear extensibility 2.8 (low); Somervell, reads 1.5: 4% of the town, peak linear extensibility 1.5 (low); Arents (not rated): 4% of the town.

Roanoke Homes by Decade

Roanoke has 4,287 homes, and the median one was built in 2007, the Census says. The 2010s brought 43.2% of them, the fourth-largest 2010s share of the 33 towns we studied. The 1990s added 20.3%, the 2000s 18.7% and the 1980s 11.4%. Only 0.2% are older than 1960.

So most Roanoke houses are young, and most likely sit on slabs. The Post-Tensioning Institute dates its design method for slabs on expansive soil to 1980. If your slab has steel cables inside, no one should cut or drill into it until they're found, and a stamp in the garage floor is a common place to look for a warning. HUD's rehab inspection guide says a half-inch crack in a new building can mean fast settling, so in a 2010s house, a growing crack is worth a prompt look.

  • 0.2%Built before 1960
  • 82.9%Built in 1990 or later

Permits and Rules in Roanoke

We couldn't confirm Roanoke's rule for a foundation repair: the city's permits page wasn't available when we checked. Before work starts, ask the city whether the repair needs a permit and an engineer's plan. Applications go to [email protected]. Nearby towns that publish a rule, such as Flower Mound and Highland Village, ask for an engineer's design.

Watering Rules in Roanoke

Roanoke's watering rules make room for foundations on purpose:

  • Any day, any time: watering by hand-held hose, drip irrigation, soaker hose or tree bubbler. The city says this is meant to allow "for the protection of structural foundations" and trees.
  • Sprinklers: two assigned days a week. If your house number is odd, your days are Sunday and Thursday; if it's even, Wednesday and Saturday.
  • Never on Mondays, and no sprinklers between 10 a.m. and 6 p.m.

So a soaker hose on your foundation is allowed whenever you need it. The Texas engineers' guidelines favor soil moisture that stays near even on all sides of a house, and they caution against overwatering, so steady beats heavy. NOAA's Roanoke station averages 39.75 inches of rain a year, with May the wettest month at 4.67 inches. Our watering guide covers timing and amounts.

Lake and Flood Notes for Roanoke

The Corps of Engineers lists Roanoke among the towns around Grapevine Lake, which was made by damming Denton Creek and finished in 1952. Around the lake, the Corps holds a flowage easement on private land at and below the 572-foot contour. Any structure or work inside that line needs the Corps' written permission, and the easement may not show on your deed or plat. Deed records are at the county courthouse. For questions about work near the line, the Grapevine Lake Office is at (817) 865-2600.

FEMA's flood map reaches into town as well. Of our 25 land points, 3 fell in the 1%-annual-chance floodplain. Our points are more than a mile apart and take in creek valleys, so look up your own address on FEMA's Flood Map Service Center.

Roanoke Foundation Repair Questions

Can I water my foundation any day in Roanoke?

Yes, by hand-held hose, drip, soaker hose or bubbler, any day and any time. The city says that allowance is there to protect foundations and trees. Sprinklers have assigned days and never run on Mondays.

Why might my neighbor's foundation behave differently from mine?

Because the soil changes so much across Roanoke. In our sample, two neighboring points a little over a mile apart landed on Aledo gravelly clay loam, reading 2.8, and Sanger clay, reading 9.1.

Who do I ask about a repair permit in Roanoke?

The city itself. We couldn't confirm its rule from its pages, so email [email protected] or call before work starts.
